Samsung Galaxy Flip 4 battery expectations

Written by admin

batteries. The only critical area where modern technology falls short. We have smartphone screens that can bend and yet we still use battery technology from the 1960s. The lithium-ion battery is still king, and it will most likely remain unchanged until solid-state batteries come along.

Speaking of bendable displays and batteries, the exact battery capacity of the Samsung Galaxy Z Fold 4 was leaked not too long ago. But what about the Galaxy Z Flip 4? What battery capacity will this (best-selling) form factor have? Let’s try and find out!

Will the Galaxy Z Flip 4 have a bigger battery than its predecessor?

That’s an important question, and since the Galaxy Z Flip 3 is Samsung’s best-selling foldable model (and the best-selling in the world in general), expectations are high for the Galaxy Z Flip 4. Although some early rumors claimed that the new model retains the previous generation’s 3,300 mAh battery, there are some new leaks (via Galaxy Club) which paint a different picture.

How much battery does the Galaxy Z Flip 4 have?

According to these leaks, the Galaxy Z Flip 4 will indeed have a larger battery than its predecessor. The new model will reportedly include two batteries (just like the Z Flip 3) with product numbers EB-BF721ABY and EB-BF722ABY.

These two batteries would have a capacity of 2,400 mAh and 903 mAh respectively. Now you are probably doing the math and you get 3,303 mAh – which is indeed better than the “rated” capacity of the Galaxy Z Flip 3.

The key here is what we put in parentheses. The real capacity of the Galaxy Z Flip 3 batteries (combined) is about 3,200 mAh, but Samsung “estimates” it at 3,300 mAh. Whatever technical term you use, the fact is that the new Galaxy Z Flip 4 will probably have 100 mAh more battery capacity than the previous model.

Will the Galaxy Z Flip 4 be wirelessly charged?

Probably! The previous model does have wireless charging support (albeit only 10W), and there’s no reason the new model shouldn’t.

Now, as far as normal wired fast charging goes, the old model supports the meager 15W, and there may be an upgrade coming with the Galaxy Z Flip 4. With the slight increase in battery capacity, it’s only natural for Samsung to increase charging speeds a little.

Will the Galaxy Z Flip 4 have reverse wireless charging?

Same as the above – since the Z Flip 3 already supports 4.5W reverse wireless charging, there’s no reason for Samsung to give that up with the new generation. Whether there will be an upgrade to reverse charging speed is too early to say.

Does the Galaxy Z Flip 4 come with a charger in the box?

Unfortunately, that ship has sailed. We don’t expect a bundled charger with the Galaxy Z Flip 4, as the entire smartphone industry is slowly moving towards a more green approach and the chargers in the box were the first victim.


Most of this article is based on leaks and rumors. However, once we get our hands on the Galaxy Z Flip 4, everything will change. Expect painstaking and rigorous testing – we’ll be testing the phone and comparing its battery life to the latest generation, as well as some competitors in this fairly new category of foldable flip phones. Until then, check this space regularly for updates on all things Galaxy Z Flip 4 battery.
